Description

Internal rotating lock

Technical field:

The utility model relates to the tapered end of a kind of lockset, particularly a kind of inward turning.

Technical background:

The existing machinery cylinder lock is very easily opened with omnipotent key, 98234206 patent application application number was disclosed on the disclosed Chinese patent CN2399488 is on October 4th, 2000, this patent application discloses a kind of mechanical billiard and magnetic bullet combination lock, when knowing the internal construction of this mechanical billiard and magnetic bullet combination lock, be not difficult to open it, but can not place too many magnetic bullet because of its inner space is limited, the number of combinations of its magnetic bullet generally has only kind more than ten, so in case after knowing its internal construction, only need just can open it with the method for souning out repeatedly in conjunction with corresponding magnetic grain, so its theftproof performance is also not high with disclosed method for unlocking in this patent application.

Summary of the invention:

Technical problem, the purpose of this utility model provide a kind of Internal rotating lock that is difficult to omnipotent key unlatching, and it has solved the not high problem of theftproof performance in the existing tapered end.

Technical scheme:

The purpose of this utility model is achieved in that a kind of Internal rotating lock, comprises key, shell, slotted vane, false sheet, slide block and spring; It is characterized in that offering some gathering sills vertically in columniform lock core periphery, corresponding groove is built-in with slide block, and a lock fork extending radially out outside the lock core along lock core arranged on the slide block; Be provided with back-moving spring between slide block and lock core; Lock core sleeve has some false sheets, has breach on the false sheet and can allow the lock fork on the slide block that slides in the groove of lock core pass through when slide block slides; Be provided with a slotted vane in described some false sheets, the height of the thickness of this slotted vane and the lock on slide block fork is suitable, forms a groove between slotted vane and adjacent false sheet, and the lock when the key of correspondence inserts tapered end and rotates on the slide block is pitched and can be entered in this groove.

Described Internal rotating lock is characterized in that lock core central authorities are provided with a counterbore vertically, and counterbore is built-in with spring, and spring top is put one and sealed post; When key does not insert in the tapered end, described spring will seal the outside top of post and the key mouth is sealed in the end of sealing post.

Described Internal rotating lock is characterized in that not of uniform size the causing of breach on described each false sheet.

Described Internal rotating lock, the thickness that it is characterized in that described false sheet is greater than the lock height of fork of slide block.

Beneficial effect, owing to adopted technical scheme described in the utility model, the breach that is enclosed within on the outer some false sheet of lock core is not of uniform size, advance the breach on the false sheet and can not unblank owing to the position that can't feel out the slotted vane place makes lock fork mistake on the slide block when unblanking, improved the theftproof performance of tapered end greatly with omnipotent key.

The drawing explanation: the 1-shell, the 2-lock tube, the 22-lock tube, the 3-lock core, the 4-key, the 41-roof limb, the 5-slotted vane, the false sheet of 6-, the 61-breach, 7-seals post, the 8-slide block, 81-locks fork.

The specific embodiment:

Fig. 1 is the internal construction schematic diagram after an embodiment of Internal rotating lock described in the utility model rotates an angle when the insertion key and with lock core.

In conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 5, Fig. 6, Fig. 7, Fig. 8 as seen, described Internal rotating lock comprises key 4, shell 1, slotted vane 5, false sheet 6, slide block 8 and spring; Offer some gathering sills vertically in columniform lock core 3 peripheries, corresponding groove is built-in with slide block 8, a lock fork 81 is arranged on the slide block 8 outside lock core 3 extends radially out lock core 3; 3 of slide block 8 and lock cores are provided with back-moving spring; Lock core 3 is outer to be positioned at outside the front and rear part of lock core 3 and to be with

lock tube

2 and 22, and be with some false sheets 6 outside the lock core 3 between two lock tubes (2 and 22), have on the false sheet 6 and lack 61 and can allow the lock fork 81 on the slide block 8 that in the groove of lock core 3, slides pass through, and not of uniform size the causing of breach on each false sheet (as represented breach on the false sheet of Fig. 7 and Fig. 8), the thickness of false sheet 6 and slide block 8 fork 81 the height of locking quite makes lock fork 81 on the slide block 8 can stretch in this breach and the adjacent formed groove of false sheet; Be provided with a slotted vane 5 at some

false sheets

6 and 22 of lock tubes, the height of the lock fork 81 on the thickness of this slotted vane 5 and the slide block 8 is suitable, 22 of slotted vane 5 and adjacent false sheet 6 and lock tubes form a groove, and the lock fork 81 when the key 4 of correspondence inserts tapered ends and rotates on the slide block 8 can enter in this groove; Lock core 3 central authorities are provided with a counterbore vertically, and counterbore is built-in with spring, and spring top is put one and sealed post 7; When key 4 does not insert in the tapered end, described spring will seal post 7 outside tops and the key mouth is sealed in the end of sealing post 7.

Fig. 4 is the key 4 that Internal rotating lock described in the utility model uses, from Fig. 4 and Fig. 1 as seen, roof limb 41 when key 4 inserts in the tapered end on the key 4 makes slide block 8 move to lock core 3 along the groove on the lock core 3, make the lock fork 81 on the slide block 8 just be positioned at slotted vane 5 residing positions, at this moment rotate key 4 and get final product rotational lock core 3, the lock fork 81 on the slide block 8 then enters the rotation that can not stop lock core 3 in slotted vane 5 and lock tube 22 and the false sheet 6 formed grooves.
